Apparatus and systems are disclosed and include a body having a plurality of slots. Each of the plurality of slots includes a first portion, a second portion, and a third portion. The first portion is located on a first surface of the body. The second portion is located on a second surface of the body and forms a helical shape. The third portion is located on a third surface of the body. The first surface and the second surface are non-parallel. The third surface and the second surface are non-parallel. The apparatus includes a plurality of antenna elements that are disposed in a respective one of the plurality of slots. The plurality of antenna elements is configured to receive radio frequency (RF) signals. The apparatus includes a ground plane that is coupled to a first end of each of the plurality of antenna elements.
